Fuel pumps are an important requirement for motorcycle fuel systems since they supply the right fuel that enables performance. Damage may occur after some time and this calls for testing and replacement of the product.
OSIAS, owned by OUTONG AUTO SPARE PARTS INC, offers a motorcycle fuel pump of high standard single/dual system in-tank fuel pump.
Symptoms of Fuel Pump Failure
It is possible to experience several signs of a faulty fuel pump. Nonetheless, the frequent signs include:
1. Decreased Performance
If you drive your Harley and find it difficult to accelerate, it can be a sign of a faulty fuel pump.
2. Difficulty in Starting
Slow engine starting could be attributed to a faulty fuel pump because of inadequate fuel supply.
3. Engine Stalling
A failing pump may struggle to maintain the required fuel pressure, causing engine stalls, especially when the temperature rises.
4. Surging
If the bike seems to gain speed without any throttle input, it is usually a sign of irregular resistance in the fuel pump motor.
Identifying a Malfunctioning Motorcycle Fuel Pump
If you think you have a defective fuel pump in your motorcycle, you can use any of the following ways to gauge the efficiency of the fuel pump.
Testing Your Fuel Pump
Wait for the engine to cool, switch off, and turn the fuel petcock to OFF position.
Test 1: Listening Test
- Select the “ON” setting on the ignition.
- Pay close attention for any buzzing or humming noises at the gasoline tank area. This proves that the fuel pump is running and providing fuel to the other parts of the vehicle.
- If there is no sound, then it could be a faulty gasoline pump or an electrical issue.
Test 2: Fuel Flow Test
- To make sure fuel is getting to the engine, you can run a fuel flow test on your motorcycle if it permits.
- The fuel line should also be disconnected from the fuel pump output and then placed in a container.
- This can be done by turning the ignition while the car’s engine is off to the “ON” position without the engine running to see if fuel flows from the disconnected line.
Similarly, if you feel there is an electrical issue with your motorcycle, you can also remove the fuel pump and spin it with a battery.
Test 3: Fuel Pressure Test
To ensure that the fuel system pressure is in conformity with the manufacturer’s requirement, a fuel pressure test is conducted.
- A gasoline pressure gauge and all the other fittings related to the fuel system of your motorcycle are needed.
- Refer to your motorcycle’s handbook to find the fuel pressure test port on the fuel rail or fuel lines.
- Connect the test port to the fuel pressure gauge.
- To actually force the fuel pump to pump the fuel, you need to switch on the motorcycle’s power light but not start the engine.
Using the gauge, check the pressure being experienced and relate it with the pressures described by the manufacturer.
They include information best accessed using a service manual or consulting your dealer for the correct information.
